Where Do Applications Fit in Today’s Network? Run on DataCenter and Deliver Across the WAN

WAN

DataCenter


� Most applications are designed for reliable, high-bandwidth, low latency LANs

� WAN-induced bottlenecks are key barriers to application performance

—Chatty application protocols (many, many sequential roundtrips)

—High link latency, low throughput, spotty reliability

—Little bandwidth management capability

The WAN Is a ChallengeBandwidth and Latency

The Latency Problem: CIFS TrafficExample: Opening a 1MB File Over the WAN


Our customers tell us they want:– Fewer datacenters

– Fewer boxes in DC or branch

– Better utilizations (equipment and staff)

– Better user experience

How To Solve The WAN Challenge?Traditional Thinking Are Too Costly

Network

• More bandwidth• Lots of point products• Replicate data or

data centers

Applications

• More testing• Rewrite applications• Security patching

Operations

• More servers• More management tools• Re-architect infrastructure

Answer: Solutions that allow CONSOLIDATIONS

Data Redundancy Elimination (DRE)Intelligent caching of TCP’s chunks

� Reduce overall WAN consumption based on redundancy

Maintain active database of previously sent and received traffic

Send database index on behalf of traffic that has been seen before

Realize 5x – 50x compression, minimize WAN bandwidth consumption

� Compress all outbound traffic with LZ compression

Additional 2x compression beyond data suppression

Very good compression for non-redundant data
